How are the parents responsible?
Do you believe that 14 year olds should be under constant visual supervision?
Do you believe that 14 year olds are incapable of acting against their parents' wishes/values/instructions?
Did 14 year old you never act against your parents' wishes/values/instructions?
Would you ignore an adult male entering your teenage daughter's (substitute sister/niece/cousin as necessary) room in underwear and causing them injury (even if slight)?
The enthusiasm of people to be judgemental over issues in which they have almost no factual knowledge is frankly depressing.
According to the older sister they were known to play this game often, and the parents didn't care. That's the problem. If you have had an upbringing of respect you are unlikely to do this, and certainly less likely to push it so far.
That's the fail to me, not a moment of failure but years of it.
Also, clearly the mum was in a nearby room. The game didn't look very quiet. Even if they were apparently supposed to be watching a horror movie. And they were already asked to stop by an adult. This had been going on a while.
Doesn't excuse MvdP at all. And he is still paying for his wrong choice and behaviour. But let's not pretend this is acceptable behaviour, because "children".
I also fail to see how identifying themselves and doing media is helping their kids/family. Even if they are upset and disputing the MvdP narrative
